Assholes don't do remorse.

In 1970, the German leader visited the Monument to the Ghetto Heroes in Warsaw and solemnly sank to his knees in a moving gesture of atonement.

The inspiring photo showed the world how to apologize for genocide.  

It vividly memorialized: “One picture is worth a thousand words.”

Asked why he did so, Chancellor Brandt answered:

 “Under the weight of recent history, I did what people do when words fail them. In this way I commemorated millions of murdered people.”

We were earlier on into how we could recognize assholes, and besides that, it's also the things assholes just do not do; assholes don't do remorse.
